Referring to the figures hy characters of reference l designates apallet in the form of an open frame the end portions of ivhich aremounted on cross stripsQ suitaloly fastened to the pallet. Formed on thepallet or secured thereto is a rile 8 extending con# tinuously along thesides and ends but spaced Another rib d is extended continuously alongthe sides and ends of the palletat the inner edges thereof. Secured tothe bottom of the pallet at the sides thereof are plates 5 the ends ofwhich project outwardly from the sides and are formed with slots 6.

Side panels 7 are adapted to loe supported inupstanding positions hy theside portions ofthe pallet l7 these panels being iitted against theouter'sides of the rib 3. Each tongues l8 extending downserted into theslots 6( Grooves 9 are provided in the inner spaces of the side panelswhere they 'will receive the ends of end panels l() mounted on the endportions of the pallet 1 and hearing against the adjacent- Slots ll areformed in the side panels 7 and projecting through these slots aretongues 12 extending from the ends of the end panels l0., These tonguesare provided ivithslots 13 for the reception of wedges ld. lt ivill heapparent, therefore, that by :inserting these wedges the side and endpanels Vwill he held together securely and will be maintained at theproper angles to each other by the rib 3,

The inner form of the mold is made up of ai'igular corner panels 'l5adapted to rest upon the pallet l and to loear inwardly against the rib4C. One portion of each coi ner panel forms part of one side of the formWuhile another portion of each corner panel forms a part ofone end ofthe form. When the four corner panels are properly mounted they will hespaced apart at their ends as indicated, for example? at 16, theadjoining ends oi the panels being inclined so as to convergedownwardly. A wedge 1T is adapted to be inserted between the downwardlyconverging ends ot' the corner inembers or pauels5 each wedge beingsecured between two face plates 18 which project be- `yond the edges oi?the wedge. The wedge is ot substantially the salue thickness as thepanel so that it can be inserted downwardly between the converging endsot the panel while at the same time theplates 18 will lap the outer andinner faces respectively of the panels. This has been clearly shown inFigures 2 and 4. Braces A19 can be secured in the angles of the cornerpanels so as to prevent distortion ot the form after it has been set upon the pallet. i

The parts thus 'tar described are assembled by erecting the panels 7 and10 on the pallet and securing them together by means of the wedges 14.The inner form is then `erected on` the pallet and the corner sectionsthereof are adjusted by means of the wedges 17 until the inner form isproperly positioned relative to the outer 'form so that the spacebetween the forms will be ot uniform width. The concrete is then pouredinto this space and allowed to set. Before this is done, however, acover plate 20 is positioned on the inner form so aste support thatportion of the concrete which is deposited on the inner form. The rib 8will produce al continuous rabbet in the edge portion of the moldedarticle7 it being understood that the body portion B of the vaultisproduced in this mold. The rabbet referred to has been indicated at R inFigure 14. After the body portion has thus been formed in an invertedposition as shown in Figure (i,I it can be turned over and will then beready to receive its cover.

For the purpose of producingthe top of the vault a. mold `such as shownparticularly in Figures to 13, is used. This mold includes a pallet inthe torni of an open frame 21 having cross strips 22 for supportingthesame. Tongues Q3 are extended laterally from the bottom of the palletand have slots 24 therein. A rib 25 is formed on or secured to thepallet and extends continuously therearound, this rib being spacedinwardly from the edges ofthe pallet. Side panels Q6 are adapted to bemounted on' the side portions of the pallet and have tongues 2T securedthereto and extendingr downwardly there from for insertion into theslots 2l in tongues E23. Each of these side panels 26 has grooves 28 inits inner side for the reception of the ends otheend panels 29 andtongues 30 are extended from the ends `of the end panels through slots3l in the side panels 26, these i tongues being adapted to receivewedges 32 whereby the panels 26 and 29 are held together securely. i

The top plate of this mold is formed of `thereof as shownV opposedi'ranies 33 each of which is provided with an arcuate top 34-, the topsot the two 'trames being' hingedly connected as at 35. The meeting;rportions` ot the :trames arc beveled as shown at lo so that it is thuspossible 'for the 'l'raines to partly collapse as shown in Figure 13.iliny .suitable means such as hook ST and a lui;- 3B are ln'ovided forholding the frame extended as shown in Figure 12. lVhen the strinftureis thus ex tended-itis adapted to rest upon the pallet 21 against theinner surfaces ol' the rib as shown `particularly in Figure 9. 1With theparts thus located the concrete of `whiclfi the top of the vault is tobe formed is poured into the mold and over the top at C in Figure 9. Byproviding the rib 2:5 located as shown the molded cover C will beforn'led with a con tinuous rib C (see Figure 14) which is adapted torest in the rabbet l-l of the body portion ot' the vault.

After the cover `has been molded `and properly set, the saine isinserted and thereafter the mold can be readily disengaged therefrom.The pallet can be easily lifted fromengagement with the tongues 23 afterwhich the side panels can be readily disen gagged from the end panels.`By then icollapsing the hingedly as shown in Figure 13, they can bedisengaged from and removed from the molded cover. y l

In some forms of molds it is desirable to provide the pallets withbracing means to prevent sagging. One such arrangenient has beenillustrated in Figure 15 ywherein the pallet 39 has been shown providedwith a. strut t0 extendingr longitudinally there under and anchored atits ends to the pallet as shown at 41. y y I Obviously instead offormingr this mold n of wood, as shown, it can also `be made ol metal.such construction requiring but slight modilications in thearrangen'ient and con struction oi the parts.

lVha-t is claimed is.: i

1. In a mold the combination with and a collapsible outer forni yreinovaliily mounted thereon. of an inner forni including al pluralityof angular corner panels, one ot said panels beingr provided for cachco1'- a `pallet ner of the inner form, the said panels being spacedapart at the centers ot the sides and ends of the form. wedgesinsertible down wardly between the panels within the respective spacesbetween the` ends thereof, said wedges being independently adjustable1and means carried by each wedge and cooperating with the engaged panels:tor holding the wedge against lateral displacement relative totheengaged panels. i

2. In a. mold the combination with a pallet and a collapsible outer form`mounted thereon, of an inner form Consisting ot i t connected framesSi? idf) and widths,

angular corner members, said members being' spaced apart at their endsand having said spaced ends converging downwardly, wedges insertibledownwardly between the oonyerging ends of the corner members, thereby toadjust the inner form to different lengths said wedges being separatelymovable, and face plates upon opposite' faces of each Wedge for lappingthe ends of the engaged corner members, thereby to hold the Wedgeagainst lateral displacement relative t0 said members.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature.
